New research suggests that combination birth control pills, oral contraceptives that contain estrogen and a progestin, don't affect milk production. Still, consider waiting until breast-feeding is firmly established — about six to eight weeks — before using this type of birth control pill.

Do I need my health care provider's OK ahead of time?

If you plan to take medication while breast-feeding, it's always best to check with your health care provider first.

Also ask about the timing. For example, taking medication immediately after breast-feeding might help minimize your baby's exposure. However, different drugs peak in breast milk at different times.

What if my baby has a reaction?

When you're taking medication, be sure to watch your baby for any unusual signs or symptoms — such as a change in eating or sleeping habits, fussiness or a rash. If you notice any change in your baby's behavior, contact his or her doctor.
